When ive been playing games as of late, my gfx card seems to be resetting itself. The screen will go black and after say 5 seconds, the fan will start itself up again, much like when you first turn on the computer. I was wondering if anyone knows anything that could help. The temps also seem to be fine-ish, for an ATI that is (50c). The rest of my system is:
3700+(Stock)
1gb corsair XMS
460w Thermeltake PurePower.
oh ya, ive OC'd abit in the past, but that was using the optimal settings in CC, but it is now at stock.

Also does anyone know a way of giving my gfx card a good test before sending it in, to be on the safe side hehe.
